You don’t always have to reinvent the wheel to create useful products. Rethinking old ideas is important too. Take this Flat Extension Cord concept. We have all tripped over wires in our homes or offices in the past. This concept aims to fix that by using circuit-printing technology and electrostatic paste material. It sticks to the floor but you won’t have to tripping over anything. Chen Ju Wei is behind this idea. We do wonder whether this solution is completely safe though.
